It's a change in throttle response. NOT turbo lag. Same volume of air is flowing through the turbo at the same velocity as it was before the FMIC install. The difference now, as many have stated, is that the distance between the compression point (turbo) and throttle plate has grown by eleventybillion feet. Making for less responsive throttle inputs.

A new tune will account for the change in pressure drop across the old TMIC and new FMIC, and maximize the charge cooling gain with the FMIC. But you won't see a magically noticeable increase in throttle response. Just something to get used to.

BUT, do yourself a favor, and do a leak check at all the FMIC pipe couplers. Most often you'll find a leak somewhere that is making the throttle response even worse than it should be.

I don't really give a crap what your opinion is on my setup. That's how it is. I asked for reasons this might be causing a delay in throttle response, not for a lecture on reasons you don't like a FMIC., but instead you feel the need to take subtle stabs at me as you do in half the threads you post in. I'm done reading this thread, I'll ask my tuner.

Get a tune... ASAP. You can drive around, but stay off the throttle and out of boost. There's a reason you're feeling this 'delay'. Your fueling is tuned for a TMIC. With the FMIC, boost takes a little longer to get to your engine, so it's creating a 'choppy' section in your power band that can be smoothed out with a tune. Resetting your ECU will not magically fix this...

It's a MAF based system. Fueling stays the same. A tune will help, but not for the reasons above.

You just gave yourself the best advice about what you should do to make it better.

When did an EBCS start becoming a fix all around here? Lots of stupid in this thread.

Fix all? I did not say that at all. Read again and I said there would be improvements when you combine the EBCS with some specific tuning changes. Don't get me mixed up with some of the people here that are not talking from knowledge and experience.
